黄河下游傍河水源地开采对水循环影响的研究

Study on the Influence of Exploitation at Water Source Area Near River-Side on the Lower Yellow River to Water Circulation

通过建立地下水流模拟模型,对傍河开采给黄河下游地下水循环、侧渗量及径流量带来的影响进行了分析。结果表明:①在黄河下游悬河段建立11个傍河取水的地下水源地,有利于水资源的多年调节和合理开发利用;②傍河取水改变了地下水的循环途径,有利于水资源的合理转化,有利于“三水”转化和改善水质;③傍河水源地大规模开采不会对黄河径流量产生明显影响。

It analyzes the influence of exploitation near the river to the phreatic cycle,lateral seepage and run-off amount of the lower Yellow River through establishing an under-flowing simulation model.The outcomes show that a) to build 11 river-side groundwater source areas at the suspended section of the lower Yellow River which is propitious to multi-year water regulation and rational development and utilization;b) diversion near the river has changed the circulation approach of groundwater which is propitious to rational conversion of water resources,the conversion of surface water,groundwater and hygroscopic water and water quality improvement and;c) large-scale exploitation at water source area near the river can not remarkably effect the run-off amount of the Yellow River.
